I am losing hard drive space because of some deep, dark phenomenon being caused by Excel 2010. It seems like every time a user opens or closes a file, or maybe if Excel crashes (I haven't figured out which), a fairly sizable TMP file (usually around the size of the original) is left behind and never cleared out by Excel. The filename is usually a 6-8_digit_number.TMP or a combination of the original_file_name_plus_some-hex.TMP.
Why Does Excel 2010 Leave A Trail Of TMP Files

If Excel (or any other Microsoft Office product) crashes, that would be the expected behavior.
